has a "url" but no "type" · add "type": "http"

Claude Code: a url entry without type is skipped as a stdio server · id PC-051 · checked_on 2026-10-31 · license CC-BY-4.0

Error strings

Situation

You paste a JSON entry with a url into .mcp.json.

Symptom

The server is skipped with a message about a missing type.

Cause

An entry without a type is read as stdio, so Claude Code reports an error and skips it.

Fix

Add "type": "http" (or sse or ws).

Snippet

{ "mcpServers": { "myserver": { "type": "http", "url": "https://mcp.example.com/mcp" } } }

Verify

Run claude mcp list and confirm the server is no longer skipped.
